One development was a sprocket lock to prevent icing under the pad break & between the track. We installed the test parts on several tricksters & I was able to even go up on the glacier. I loved Centennial, the little motel & diner & on the weekends the steak house down the hill.

    John: I don't know where the SN part was shot. If you were there, Most reasonable people would believe you. I think the outboard part was at Lake Carol in Ill. prior to the race. Johnnie Sanders drove the boat and as you can see he didn't get up to speed for the camera. I want to remember it was a potato chip commercial as I remember the good looking gal trying to hold the bag without wrinkles and the photographer told her to straighten it out and they could edit that part out. The sound was obviously dubbed in.

    Mazda exec details plans for rotary range-extended EV coming in 2019

    Tesla gets a lot of flak for its delays in promised technology, but the electric car company looks like a straight-A student next to Mazda which has been has been talking about reviving the rotary engine going back to the demise of the RX-8 sports car in 2012.

    Mazda says it is committed to the rotary, though the automaker has flip-flopped over whether the engine will be used to power a sports car or simply serve as a range-extender for an electric car. We've seen concepts for both, and just last year a Mazda executive said the company may end up going with both options.


    A Message from Southeast Toyota

    Time to take on the day.

    Now Mazda's sales chief in Europe, Martijn ten Brink, has revealed to Dutch group AutoRAI that Mazda's electric car launching in 2019 will be available with a rotary range-extender. The exec said the electric car will be based on the same underpinnings as the next-generation Mazda 3, and hinted that a crossover body style would make sense.

    We also have a few details on the rotary range-extender itself from ten Brink's interview. He said it would be a single-rotor engine without a turbocharger. He also said the compact design should take up no more space than two shoe boxes, and because of the smoothness of the rotary engine, drivers of Mazda's electric car may not even notice when the engine is operating.

    mazda re
    (Mazda)

    Mazda has already shown an electric car with a rotary range-extender: the Mazda 2 RE Range Extender concept unveiled in 2013. Its rotary was a single-rotor 0.33-liter unit that with a full tank of gasoline could provide an additional 111 miles of range. Based on ten Brink's comments, it's likely a similar setup will feature in Mazda's electric car due next year.

    Unfortunately, ten Brink didn't have anything to say on a rotary-powered sports car from Mazda. The Japanese firm has struggled with meeting emissions regulations with high-performance applications of its rotary engine. The company has also described building the business case for a sports car as another issue. Those are two major factors standing in the way of a new rotary-powered sports car.

All I could think on the way to the crash site was diving into the water and having that alligator show up. As we got closer we saw Rich bobbing behind the boat. The front of the boat sticking out of the water had blocked our view of him. I dove in and grabbed Rick. He was mad as a hornet, but not hurt.

    Big Gators are a real concern for race drivers bobbing in the waters of Florida.

About half way thru the second day, the driver got it too high out of corner and blew it over backwards. The water was only 10 ft deep so the motor end went to the bottom and the front stuck out of the water. We could not see the driver and feared he was stuck in the boat under water. Jack Leek and I were in the chase boat and started immediately to the crash sight. Unfortunately, we didn’t even get on plane and the engine quit. Franticly we tried to figure out what was wrong and restart the engine. We had run out of gas! After quickly changing tanks we rushed to the sight. On the way there I stripped down to my skivvies ready to dive in and rescue the driver. The day before we had seen a 12 ft alligator lying on the shore but today he wasn’t there.

    Tesla Model 3 Performance racer who got disqualified at a Global Time Attack Super Lap event at Buttonwillow Raceway Park because his car wasn’t running on an approved fuel type—i.e. gasoline.

    https://jalopnik.com/that-tesla-mode...tac-1830414592

    Is this disqualification of the race winner (Telsa car), not unlike the OMC rotary, getting negative race politics from the Mercury team?
    Like what is the real cubic-inch displacement of the rotary engine, is it more than Mercury's six-cylinder engine.

    A smaller prop gave them better acceleration and that the HP curve was still going up at a 45 degree angle at 7000 RPM . To confirm our concerns, we put recorders on two of the Galveston engines. They recorded RPM vs time. Unfortunately, one of the recorders was on Bobby Whitt’s boat and the data was lost due to the unexpected swim. The other recorder did show above redline RPM but not terribly excessive. We took the engines back home, tore them apart and started getting ready for the next race.
